Revenue Deduplication

You can also add an optional transaction ID to avoid tracking duplicate revenues. The last ten transaction IDs are remembered, and revenue events with duplicate transaction IDs are skipped. This is especially useful for In-App Purchase tracking. You can see an example below.

If you want to track in-app purchases, please make sure to call the trackEvent only if the transaction is finished and an item is purchased. That way you can avoid tracking revenue that is not actually being generated.

var adjustEvent = new AdjustEvent("abc123");

adjustEvent.setRevenue(0.01, "EUR");
adjustEvent.setTransactionId("{YourTransactionId}");

Adjust.trackEvent(adjustEvent);

Note: Transaction ID is the iOS term, unique identifier for successfully finished Android In-App-Purchases is named Order ID.
